Window sash retainer



WINDOW SASH RETAINER Filed sept. 16; 1951 Patented Oct. 25, 1932 PATENT orrica JOHN YACOMIS, OF ALBANY, NEW YORK WINDOW sAsH RETAINER Application flled September 16, 1931. Serial No. 563,173.

This inventionr relates to an accessory for use in connection with cooperative sliding sashes used in present day window structures, and it has more specific reference to a retainer in the nature of a check applicable to one of the stiles of an upper sash and located for coaction with said sashes to limit the relative sliding movement thereof whereby to restrict the opening to provide for appropriate ventilation and preventing intruders from gaining entrance because of the restricted proportions of said opening.

vWindow sash checks of this general classication and used for the same purpose are not broadly new. In fact, the art to which the invention relates is sufliciently well developed as to permit denite recollection of the fact that, generically speaking, prior art devices employ projectable and retractable elements adapted for disposition in the path of movement of the corelated sashes to accomplish the purposes previously stated.

A primary purpose of the invention of this application is to generally improve upon known prior arts and marketed checks and retainers by providing one which is structurally different and characterized by such improvements and refinements as serve to produce a novel contribution to the art.

The explicit features and details which serve to characterize and distinguish my improved sash check will become more readily apparent from the following description and drawing.

In the drawing:

Figure 1 is a fragmentary front elevational view showing a pair of window sashes with the device in position on the upper sash.

Figure 2 is an enlarged fragmentary vertical section on the line 2 2 of Figure 1.

Figure 3 is a perspective view of one of the essential parts of the invention.

Figure 4 is a perspective view of the projectable part hereinafter referred to as the spring pressed bolt.

In the drawing the numeral 5 designates the window frame which is conventional, and 6 indicates the upper sliding sash while 7 denotes the lower sash. These sashes are also of ordinary construction. In accordance with the invention one vertical stile of the upper sash as indicated at 8 in Figure 1 is formed with a mortise or socket to accommodate the parts 9 of the attachment. This mortise serves to accommodate the open end-V ed tubular barrel 10 constituting an kintegral part ofthe attaching panel or plate 11. r `his plate may be of any suitable conliguration so itis preferably of an elongated shape depicted in Figure 3. It has its upper and lower end apertured at 12 tok accommodate a fastening screwl?) as seen in Figure 2.; In fact the stile or rail of the sash may be recessed tofallow the plate to fit in flush with the surface of the rail. The plate 11 is formed at a point above the horizontal rbarrel 10 with a vertical slotl 14 adapted to accommodate a headed stud 15.0n` a 'slidable gravity retain-V ing latch 16.V This latch is of any appropriate configuration and formed with a finger 70 button to facilitate operation thereof.

In alinement withthe barrel the plate is formed with a circular' hole 17 which is here shown as of a diameter less than the barrel so as to provide a substantially annular abutment. To one side this hole or aperture 17 is formed with a notch 18 which constitutes a keyway.

The keyway 18 serves to accommodate a longitudinal rib or key 19 formed on the surface of the. cylindrical bolt 20. At its inner end this bolt is provided with a disk likehead 21. The bolt is of a diameter to correspond to the aperture 17 andthe head 21 of a diameter corresponding to the internal diameter of the tubular barrel 10. v v

In addition the rib 19 is of a length less than the bolt so as to provide a terminating space at the outer end` of the bolt and allowing the adjacent end of the rib to function as a shoulder 22. The numeral 23 designates a coil spring which is housed in the barrel and which bears at its inner end against the socket drilled in the window stile and at its outer end against the head ,21. The spring exerts an outward normal thrust against the bolt so that when it is released it is projected to the dotted line position as shown in Figure 2; `When thus projected' the 'bolt constitutes a check and is in the path of movement of the sashes 67 thereby limiting the sliding movement thereof and restricting the top and bottom opening.

As before stated the purpose of this is to provide for ventilation and at the same time provide for safety by preventing intruders from gaining entrance through open windows.

Particularly do I wish to call attention to the one piece construction of the part 9 characterized by a simple attaching plate 11 and horizontally disposed open ended barrel, said barrel being of a diameter greater than the bolt holes 17. Moreover the gravity actuated slidable button or latch 16 is an important feature in that it is easy to lift for releasing the bolt and automatically drop to a position for retaining the bolt in a retracted position. The unusual cooperation of the shortened rib or key 19 in the notch 18 is another desirable feature and the use of Said rib as a shoulder for cooperation with the latch is an added feature. Then too the idea 0f havin the barrel 10 open ended adds to the Simp icity and economy of manufacture of the part 9 and facilitates assembling and repair, there being no closing cap at the inner end of Asaid barrel. The rib 19 itting in the notch 18 and the head 21 sliding in the barrel 10 provides a rigid assembly and avoids disalinement and insures appro riate coopera-y tion of the details of a comp ete unit.

In operation all that is necessary when the bolt is retracted as seen in Figure 2, is to lace the finger on the button 16 and to raise 1t. This releases the bolt and allows it to be proi'rected to the dotted line position depicted 1n igure 2 wherein it serves as a suitable retainer for limiting sliding movement of the window sashes.

When the bolt is pushed in to the requisite degree latch 16 drops down by gravity to retaining position to hold the parts in a full line position also shown in Figure 2.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Having thus described my invention, what I claim as new is:

AS a new product of manufacture, a window sash check comprising an attaching plate formed with a vertical slot and below said slot with a bolt hole and a marginal notchA said bolt hole, said barrel having an internal diameter greater than said hole, a bolt of a diameter corresponding to the bolt hole, said bolt being formed at its inner end with a disk like head slidable in the barrel, a spring in said barrel cooperable with said head, said bolt bein provided with a longitudinal rib slidable t rough said notch, a gravity actuated retaining latch comprising a plate having a finger part at its upper end and a stem slidable in said slot, the outer end of said rib terminating short of the adjacent end of the bolt to form a shoulder with which the cooperating end of said latch is engageable.

In testimony whereof I aliix my signature.

JOHN YAcoMis.
